Chichikogusa

Chichikogusa is basically Mushishi if Ginko had a son and the illnesses he was treating weren't supernatural. Basically both are slice of life about a wandering middle-aged man who deals plants to ill people in preindustrial Japan.
Story about a man that has to live his life as a wanderer because of his job. Even though chichi doesn't talk about supernatural stuff, it tells a history about a wanderer pharmacist that seems quite similar to Ginko. Also the way that the stories develop gives a refreshing and calm feeling in both manga.
